12. O-ring Gland Design The following pages contain basic O-ring gland design information. Please contact the local ERIKS repre-sentative if an application does not clearly fall into these design parameters. Static Applications There are five types of static O-ring applications: • Flange seal • Radial seal • Dovetail seal • Boss seal

For the purposes of this article, we will focus on just three common rubber types found in O-rings and similar automotive seals: Buna N, Viton, 

Spliced O-Rings are an economical alternative to standard O-rings. They are created from a cord material that has been extruded and vulcanized to the desired size. Ace Seal offers seamless spliced Metric and English O-Rings, along with splicing kits. The company also offers Parker Back-Up Rings, Quad-Rings, and other O-rings and seals.

A hermetic seal is any type of sealing that makes a given object airtight (preventing the passage of air, oxygen, or other gases). The term originally applied to airtight glass containers, but as technology advanced it applied to a larger category of materials, including rubber and plastics. Hermetic seals are essential to the correct and safe

Cross-sectional diameters range from 0.040 to 0.275 inch. Inside diameters range from 0.029 to 25.940 inches. There are 369 standard sizes. ID Inside Diameter OD Outside Diameter CS Cross Section .070″ .103″ .139″ .210″ .275″. Here is an interactive chart for standard o-ring dimensions. entries.

Some of our common types of O-ring materials include PTFE, Nitrile (Buna), Neoprene, EPDM Rubber and Fluorocarbon (Viton) . Silicone and Kalrez® O-ring materials are also widely used, especially in high temperature applications.

When used as a static seal, an O-ring remains stationary to contain pressure or seal a vacuum. The dynamic form of O-ring can be reciprocating or rotating. O-rings are a self-energizing seal that applies pressure inside a tube or pipe to form a seal. Chapter 2: How O-Rings are Made

Static seals are categorized as either AXIAL or RADIAL, depending upon the direction in which squeeze is applied to the O-ring’s cross section. STATIC AXIAL SEALS A static axial seal acts similar to a gasket in that it is squeezed on both the top and bottom of the O-ring’s cross section.

O-Rings can be made from plastic or metal, but for the purposes of our blog, we'll focus solely on rubber - or elastomeric -- O-Ring design. An O-Ring, also known as a "torus," works in tandem with the glands in which they are installed. The gland is normally cut from the metallic hardware, and works with the O-Ring to seal.
